Boydstun Cylinders and Cottrell Cylinders? Couldn't be.

No, they're not Boydstun BRAND hydraulic cylinders or Cottrell BRAND hydraulic cylinders, but these are definitely aluminum hydraulic cylinders for auto transport trailers. Look to be good quality, too, not the ones that will get bent rods if you look at them the wrong way. Yup, these cylinders are guaranteed not to rust, bust or collect dust for one whole year.
